upgrading mainboard and cpu etc...

should i do a repair installing of xp using the cd first and install mainboard driver later or vice versa.

 

Are you saying you changed the motherboard of a computer and now you want to make it work with your old HD?

What you should do is reinstall windows. Swapping out a motherboard is the same thing as buying a new computer and then trying to move your HD over to it and expect everything to work.

If you REALLY don't want to do a fresh install then you can try the repair option, but odds are you'll have problems with it. It's not a good idea to move an OS from one motherbaord to another. Windows doesn't make any claims to support such a move, so if you do it it's asking for problems.
